Horsetan Posted September 10, 2012 Share Posted September 10, 2012 As a sort of sub-thread to my GNR(I) "S"-class project, and "Weshty" was after asking anyway, I thought it might be of interest if I posted up some of the motors and gearboxes that I prefer to use. Wherever possible, I like to use coreless motors and reversible drivetrains. Best example of this is the Escap RG4 which came in three sizes: 1219 (the motor was provided by Faulhaber, not Portescap): 1616: and 1624: They were widely available from the late 1970s until about 2005, when difficulties in supplying the gears meant that these combinations disappeared from the market. They now command fairly high prices on eBay. Fortunately I bought most of mine when they were in production and accumulated about 20 of them. The great thing about coreless motors is the very low current consumption needed to get them started, whilst the bevel-and-spur gears don't lock up when the power is "off". You can hand-push a model and its wheels will keep on revolving; you can't do that with worm drives. The motors themselves are still being made and are fairly easy to get hold of. My question is: is there not a gear maker in Ireland who could reproduce the bevel-and-spur geartrains at a reasonable price, so that more people can use them?
